<p>PROBLEM TO BE SOLVED: To accurately detect an insulation resistance value of a noncontact power supply and accurately detect whether an earth fault is present.SOLUTION: A fuel cell vehicle 11 of a power supply system 10 comprises a fuel cell stack 21 and a battery 22 as a noncontact power supply, and an inverter device 12 comprises an inverter 71 including an insulating transformer (transformer). A control device 34 calculates an insulation resistance value on the basis of a state amount detected value relating to an insulation resistance value of the noncontact power supply detected by an earth fault sensor 35 during operation of the fuel cell vehicle 11 or during output of electric power from the fuel cell vehicle 11 to the inverter device 12.</p> |
